18QHTF21-3.656-OE

Oscillators Overview

The 18QHTF21-3.656-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 3.656 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital circuit compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics timing circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Ensure the 1.8V supply voltage aligns with the system power rails. Confirm that the enable/disable functionality is utilized correctly in the schematic to manage power consumption during inactive states.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small 4-SMD footprint if board space is limited compared to larger oscillator packages.

Oscillators Part Context

This part belongs to Mercury's QuikXO series, which focuses on fast-delivery CMOS output clock oscillators. The series offers both standard and custom frequencies built to order. Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in quartz crystals and timing components.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify frequency accuracy and pinout compatibility before substitution.
